SPECIFICATION forming part of Letters Patent No. 511,665, dated December26, 1893. Application led August 22, 1893. Serial No. 483,776. (Nomodel.)

.To a5?) whom t may concern:

Be it known that we, PAUL TRABUE and LYMAN TRABUE, both of Girard, inthe county of Macoupin and State of Illinois, have invented a certainnew and useful Improvement in Ealing-Presses, of which the following isa full, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification.

Our invention relates to an improved power mechanism for baling presses,and our invention consists in features of novelty hereinafter fullydescribed and pointed out in the claim. l

Figure I is a top view of our improved press, part in longitudinal,horizontal section, taken on line II, Fig. II. Fig. II is a vertical,longitudinal section, taken on line II-II, Fig. I. Fig. III is a detail,horizontal section, part in top view. Fig. IV is a detail, verticalsection, showing part of the pitman, and part of the cams. Fig. V is aview showing part of one of the cams, in section, part of the pitman,the friction rollers and wasliers, and the connecting pintle, the partsbeing disconnected. Fig. VIis a face view of one of the cams. Fig. VIIis a view of the beam.

We have shown our invention applied to a press of the reversible type.

Referring to the drawings, l represents the body of the press, 2 theplunger, 3 the onepart pitman, and et the sweep. These may be of anyordinary form or construction.

5 is a beam to which the sweep is secured, and which is pivoted to theframe of the press by an eccentrically arranged pin 6. To the outer end0f the pitman are journaled three anti-friction rollers by means of apintle 7. There is an upper and lower outer roller 8, and anintermediate roller 9. Between the upper and lower rollers and thepitman we prefer to place washers l0. See Figs. II and V.

ll is an upper casting and l2 a lower casting secured to the frame ofthe press above and beneath the beam respectively, and each having anelliptical depression forming a cam groove I3, t0 receive theanti-friction rollers 8, as shown in Fig. II. The beam 5, as the sweepis swung from side to side, bears against the anti-friction roller 9.The eccentrically arranged pin 6 is located near the forward parts ofthe grooves. These grooves are continuous. The movement of the sweep, ineither direction is limited by the beam coming against a lug 14 on oneof the castings l1 or l2.

Inoperating the press, the beam is moved by the sweep against the roller9 of the pitman, and the continued movement of the sweep causes theforward movement of the plunger, the rollers 8 moving in the cam grooves13, and the shape'of the grooves is such that the first part of themovement of the plunger is rapid, While as the plunger reaches the limitof its forward movement, and much power is needed, the speed decreases,and the power increases. point of bearing between the roller 9 and beam5 passes a line drawn through the pivot 6 of the beam, the plungerrecedes under the expansive action of the compressed material, therollers 8 moving in the cam grooves on the other side of the castingfrom that occupied by them in moving forward. The sweep is thenreversed, and the operation repeated.

IVe are aware of the patent issued to the Collins lrlow Company, August19, 1890,v No. 434,760, and do not claim anything therein shown anddescribed.

We claim as our invention-- A baling press comprising a plunger, aonepart pitman having upper, lower, and intermediate rollers at itsouter end, upper and lower castings, each casting having a continuouselliptical groove on the inner face thereof, the eccentrically arrangedpivot-pin located near the forward parts of the grooves, and a sweephaving a beam located on the pivot pin between the castings; the upperand lower rollers playing in their respective grooves, and the beamadapted to bear on the intermediate roller; whereby, with a singlepitman, a long range of movement of the plunger is afforded, the firstpart'of the forward movement of the plunger being rapid, and the latterpart of the forward movement of the plunger being slow and powerful;substantially as described.
